If you're asking that, you're already further gone than most. Immersive sim is more about design philosophy than a checklist-multiple paths, systems-driven gameplay, player agency over handholding. Think of it like this: if you can stack crates to reach a vent, sneak past a guard, or hack a camera instead of just shooting, you're in imsim territory. Stuff like Deus Ex, Thief, System Shock 2, Prey (2017), and to a muddier extent, Dishonored (though it leans too hard on style over simulation for purists). These days though, people slap the label on anything with choices and a first-person POV, so mileage may vary.
